`STANCHIONl SPECIFICATION forming part of Letters Patent No. 376,069, dated January 10, 18C 8.

Application filedrMarch 5, 1887. vSvrial No. 229,776. (No modeL) To aZZ whom itmayconcerm Be it known that I, DAVID Y. CLARK, residing at Bristol, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Stanchions; and I do declare the following to beafull, clear, and exact description of the same, reference being had to the accompanying drawings, which form a part olf this specification.

My invention relates to an improvement in stanchions, the object being to produce an automatically-closing device of superior convenience and combining simplicity and cheapness vof construction with durability and efficiency in use.

With these ends in view my invention conslsts 1n certain details of construction and com- -binations of parts, as will be hereinafter-de- The stanchion proper consists of a pivotalv upright, A, a stationary upright, B, an upper crossbar, C, and a lower cross-bar, D. The lower end ofthe said pivotal upright enters a slot, E, formed in the adjacent end ofthe crossbar D, which carries abolt, F, upon which the said upright is fulcrurned, and a stift spring, G, extending downward through the said slot and engaging with the projecting lower end of the upright and exerting a constant effort to throw the upper end thereof inward in the direction of the stationary upright. The upper end of the 'said pivotal upright is provided upon its outer face with an eye, H, and through said end with a horizontal aperture, H, in which is pivoted a horizontal metallic latchbar of sufficient length to extend to the opposite end of the upper cross-bar, slightly bowed from end to end, and provided at its free end with a latch-head, K, as shown. The said'upper cross-bar is provided with a slot, L, having beveled walls M, to guide the pivoted upright into the same, with a groove end for receiving and guiding the bar I, extending from the slot L to the opposite end of the cross-bar, a transverse latchbar guard, O, located adjacent to the said slot, a locking-plate, P, located at the opposite end of the bar and bent to receive the latch-bar and its head, and with a latchingspring, Q, located beneath the said plate and operating to automatically engage and lock the latch-head therewith.

The stanchion is suspended from the upper beam of a suitable stanchion frame, R, by a bolt, S, passing through the upper cross-bar at a point midway of the length of the saine. The lower connection of the stanchion and stanchion frame consists of two two armed sheet-metal angleplates, T T, pivoted together andto the lower cross-bar of the stanchion and to the corresponding bar of the frame.

A snap-bolt of1 approved construction is mounted in the stanchion-frame in position to engage with the eye H ofthe stanchion when it is desired to hold the pivotal upright of the same in its open position. As herein shown, the snap-bolt consists of the frame U, the bolt V, having the beveled nose NV, the spiral spring X, and the nger-piece Y, for retracting the bolt against the tension ofthe spring.

Havingfully detailed the construction ot' myirnprovement, I will now set forth the mode of its operation.

To open the stanchion the latch-head K is pressed down against the latching-spring Q with one hand and the head disengaged from the locking-plate I), leaving the pivotal upright A free to be rocked on its fulcruni F, whereby the stanchion is opened. Then,if it is desired to lock the stanchion open, the eye H is pressed against the beveled nose W of the bolt V, which will retire and spring forward again, when it will pass through the eye. To release the upright from this engagement the bolt is withdrawn from the eye by means of the linger-piece Y,when the spring G operates at once to throw the upright back to its normal position in the slot L, being guided by the latch-bar traveling in the groove N, which it never leaves entirely, and by the beveled walls M of the slot. Just as the pivotal bar reaches its upright or closed position the latch-head passes throughv the locking-plate P, and is lifted into engagement therewith by thelatching-spring Q, which thus automatically locks the stanchion closed. It is to be noted that as the pivotal upright is rocked back upon its fulcrum the latch-bar, being also pivotal, is drawn into the bottom of the groove and main- IOO tains the upright in line with the slot- L receiving its upper end.

A stanehion constructed under my invention is very convenient to open, a light press ure upon the latch-head with one hand being all that is necessary.

The convenience and advantages of making the stanehion seltelosing are also obvious. The stanchion may be opened and closed in a dark stable without a light, as there are no pins and bolts to remove and replace and no complicated locks to manipulate.

The link-connection described is a very [lexible one and allows a wide range of side and direct movement, the latter being received while the slanchion is in vertical position.

It is obvious that some changes in the eonstruction ot' the device may be made, and I would therefore have it understood that I do not limit myself to the exaet construction and Combination ot' parts herein shown and de scribed, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

I am aware that an automatieally-closing slanehion is not broadly new, and that the pivotal uprights of stanehions have heretofore been provided with pivotal latclrbars. I do not, therefore, broadly claim an automatically-closing stanehion or a stanehion having its pivotal upright provided with a latch-bar; but,

Having fully described my inve11tion,wl1at I Claim as new, and desire to sceure by Letters Patent, is-

l. A suspended orswinging sianchion having two uprights and an upper and a lower cross-bar, one of the uprights being pivoted to the lower cross-bar, of a spring secured to the said lower cross-bar and engaging with the pivotal upright to automatically close it, and looking mechanism earried by the upper cross-bar and the upper end of the pivotal upright for holding the latter closed, substantially as set forth.

2. Asnspended or swinging stanchion having two uprights and an upper and a lower cross-bar, the lower cross-bar having a slot at one end to receive the lower end oi' one of the upright's, which is pivotcd in and extends below the said slot, a spring scoured to the said lower erossAbar and extending through the slot to engage with the lower end of the pivotal upright,whieh it automatically closes, and locking mechanism carried by the stanehion for locking the upper end of the pivotal upright in place, substantially as set forth.

3. Asuspendcd or swinging stanehion having a stationary and a pivotal upright and an upper and a lower cross-bar, the pivotal upright being pivoted to one end of the lower eross-bar, a spring carried by the stanchion' and engaging with the lower end of the pivotal upright for automatically closing the same, a lateh-bar pivoted in the upper end of the pivotal upright and working in a slot formed in the upper erossbar, and a locking plate and spring for the said latch-barcarried by sueh upper cross-bar, substantially as set forth.

Ll. A stanchion having an upright pivoted at its lower end, a spring for closing suoli upright, and an upper cross-bar having a slot to receive the upper end of the upright and provided with beveled walls to guide the saine into it, substantially as set forth.

5. A swinging or suspended stanehion having two uprights, two cross-bars rigidly secured to one upright, the other upright being pivotcd at its lower end to the lower crossbar, a spring carried by the stanehion for automatically elosing sneh pivotal upright, an eye located upon the outer face ot' such npright, and a snap-bolt secured to framework in line with the pivotal upright in position to engage with the said eye and hold the upright open against the power of its spring, substantially as set forth.

6. A stanehion and a stanehion-frame, in combination with a connection consisting of two two-armed sheetmetal angle-plates pivotcd together and to the stanchion and stauehion-framc, respectively, substantially as set forth.

In testimony whereof I have signed this specification in the presence ol' two subscribing witnesses.

DAVID Y. CLARK.
